This consolidates the same code and also makes patch 8 (last one) be localised to the SPI core part. The last patch is the main rework to get rid of a recently introduced hack with a dummy SG list and move to the transfer-based DMA mapped flag. That said, the patches 1 to 7 may be applied right away since they have no functional change intended, while the last one needs more testing and reviewing.
